lynxpoint: Add power management helper functions

There are subtle yet significant differences in some of the
    registers in the power management region between LynxPoint-H
    and LynxPoint-LP.

In order to reduce code that is accessing these registers and
    would need special cases this adds a number of helper functions
    that can be used in both ramstage and SMM.

This commit just adds the new functions, subsequent commits will
    start to use them.
